so, I'm kind of curious.
Is there anyone on here who has experience with a MG42/M53/MG3?
I'm talking about actually using it in training or in combat.
How did you like it?
>>29562191
Shits out rounds so fast i found it hard to qual at first. Takes some getting used to after the 240.
>>29562191
Haven't even't seen one myself, but I'm curious how the high cyclic rate affects lifetime durability, or if certain countries who use them modify the cyclic rate. Also curious as to how many countries who haven't adopted them for the infantry have a few of them as a gpmg on vehicles they have bought from Germany, or Spain, etc. (thinking polish Leo2s)
>>29562191
>Modernized MG42
>>29563140
well it's not like the countries using them do anything but train so wearing out the guns isn't a huge issue xD
>>29562191
Even with the rate reducer you are limited to extremely short bursts. Its very reliable assuming you dont get mud in the barrel lock while changing barrels.
Belts are nice and there are plenty of mounts made. There are better machineguns but the MG3 is nice.
how exactly does roller delay work?
>>29564208
It delays the blowback with rollers.
>>29566268
this, basically the rollers can only roll back below a certain pressure so you can pull the charging handle back and they just slip right back. But under pressure they lock in place until the force goes under the threshold where they move freely. Has an interesting feel to the recoil and a very clean operation as there is no gastube or ports in the barrel. Rollers are however a wear item and need to be inspected every so often. Failure to do so especially in older firearms like the CZ52 can lead to them wallowing out the receiver. Rollers are dirt cheap, receivers not so much.
>>29564208
The barrel and barrel extension (it's made from a single piece) has two recesses in it. When the bolt is in battery the bolt forces two rollers out that lock into the recess.
When a round is fired the barrel and the bolt recoil backwards slightly before the barrel stops. The bolt them moves reward under its own momentum and unlocks the bolt from the barrel.
>>29566370
>clean operation
>literally blows all the gas back into the receiver
I'm not saying roller delayed blowback is unreliable at all, but compared to a piston - come on. Pistons keep most of the gas at the piston head.
the mg3 is a fucking bitch to clean
>>29562191
Fired the MG3 off the bipod
Range training only as not a tankfag
High rate of fire after M60 and Mag58 so not as accurate in beaten zone and correction onto target.
Only bipod gun ever to push me backward off the front of the mound as bipod tended to fold backwards unless I pushed fully forward and dug toes in.
>prefer Mk48 or PKM
>>29564208
Roller delayed is pretty difficult to imagine, but here.
So basically, the Bolt is two in two pieces. The bolt head, and the the rest of the bolt.
Now what is essentially protruding from the bolt and connecting the two pieces the the 'locking piece'
This locking piece is the angled bit that the rollers will 'ride' on during the recoil cycle.
When the bolt is locked forward, the inertia of it will chamber a round fully, and depress the action fully shut. When this occurs, the rollers are forced into their cavities in the trunion by the angled nature of the locking piece. However this is a fairly smooth action, since you can visuallize as per the image, they are more or less sitting in an unrestrained manner, but once they enter the trunion and the bolt gap over the locking piece as seen on a opened HK action/ the image here, the wedge shape is forced tightly against the roller. Once the gun is fired, the bolt head impinges upon the rollers. During this course of action, the rollers, that naturally want to move directly to the rear, are forced to impinge themselves onto an inward slant upon the locking piece. This accelerates the locking piece to the rear to the degree where #2 is marked in the top part, instead of no gap as seen below in a ready to fire state. From this point the rollers are free and the bolt can continue its recoil cycle as it wants.
You have to take note that how in the 2nd part of the image, where the bolt is locked and ready to fire, that the bolt head is now a component that is taking the brunt of the recoil energy initially. And because the location of the rollers, that force is being directed inwards inefficiently onto the angled locking piece, which then pushes the rest of the bolt back unlocking the action as the rollers are freed to drop inwards.

>Fucking fast, even the castrated (i.e. non MG-42 versions with ROF of about 1000)
>Barrel change is as quick as magazine change on an assault rifle (if you're trained)
>Gets heavy after 20 Miles
>Gets hot everywhere after long time of sustained fire
>Easy to hit targets after you get used to the high ROF
> Wonderful bipod that can be mounted at the front or in the middle of the weapon
> Sometimes a scope would be noice

Is it that hard to burst appropriately?

In what respects?

not him,but:
>complicated design
there are a lot of moving parts inside an MG3 where as other MGs have much fewer
this leads to more frequent stoppages
>high rate of fire
this has a negative effect on accuracy and consumes ammo really fast
>free floating barrel
this also contributes to low accuracy, an mg with a barrel that's clamped down/screwed in place is more accurate
>>29568192
>free floating barrel
>bad for accuracy
That's new.
>this has a negative effect on accuracy and consumes ammo really fast
Is this not a matter of trigger control? You'd think putting more rounds on target in less time would be conducive to scoring hits within a given window of opportunity.
>>29568192
>this leads to more frequent stoppages
That's the theory. But for an actual comparison one would need to perform a controlled test between different MGs in order to determine the mean rounds between stoppages.
And accuracy matters on the shooting range. In combat rate of fire is more important.
>>29568192
t. armchair general
rofling @ u desu
>>29568192
I've never heard the MG42 design as being prone to stoppages. Seems like a much better gun than the M249/Minimi ever was.
>>29568192
We found it lads. Most retarded post of the day.
>>29563896
>xD

>>29568457
>That's new.
It's because free floating barrels on an LMG is something completely different than a free floating barrel on something like a bolt action rifle for example.
>>29568457
>You'd think putting more rounds on target in less time would be conducive to scoring hits within a given window of opportunity.
other LMGs aren't exactly slowpoke. they deliver rounds quick too. MG3 just has an over the top firing rate.
>>29568477
the complete bolt-assembly consists of something like 16 individual moving parts, 13 of them being parts that the user needs to clean during maintenance, all these parts need to work together flawlessly
the basic FN MAG-design on the other hand consists of two such parts
>>29568487
>>29568492
police that asshurt pls
>>29563140
There was some issue with the rolling pins, so the cyclic rate was gimped in favor of less jams later on in WWII.
>>29562191
Fucking heavy while you carry it on marches, fucking awesome as soon as you have it on the ground ready to go.
Firing single shots(weird training but the Budneswehr did those) and short bursts are fairly accurate. Can't say how it handles longer bursts accuracy-wise since I only did those during training with blanks.
All in all I rate 8/10 but my opinion isn't representative, since it is the only beltfed MG I used for a longer period of time. A BREN is more controllable imo.
>>29568637
>other LMGs aren't exactly slowpoke. they deliver rounds quick too. MG3 just has an over the top firing rate.
By what metric? Your guts?
>13 of them being parts that the user needs to clean during maintenance
So, you've never had the MG3 as a service weapon.
I've had one in my hands in 2008 wich had the 42 x'ed and a 3 stamped instead, still in use at this point
Fiering in "pirschaltung" is very amusing also.( gun at hip hight,lace around neck and one hand at the bipod)
>>29568716
>So, you've never had the MG3 as a service weapon.
I have, in fact. Maybe you don't clean those 13 parts after every time you've been to the range. But they're still there. And they must be cleaned some time.
Also very funny is hipfiering two of this very classy ladies
>>29568716
>By what metric
by the fact that its recoil affects accuracy and consumes ammo too fast, which is why I wrote "over the top"
>>29568716
Not tha guy but also trained as an mg3 gunner. After 500 rounds of continued fire you got to swap the barrel or rounds may start getting stuck in the barrel.
Luckily this barrel swapping is pretty fast but you either got to use the oven mitt that comes with it or a leather glove,this shit burns.
Was great with nomex flight gloves.
Fired blanks with it from a window (tripod) lit the window frame on fire and the barrel was glowing blue and white.
That was pretty neat.

>>29566774
MG3 is recoil-operated, roller-locked, not blowback-operated.
>>29566453
Is the only one that got it right.
I would say, if you are well trained in maintenance and shooting this gun and are physicaly capable to carry the ~ 15 kg with an solid amo-box, it is an very usefull instrument of warfare
>>29568791
After 1200 as a practce we swap out the lock/bolt (not sure what the correct translation is) we carry the other one in a grip bag that is dosed with gunoil.
Also carry a cokebottle of some more oil to pour all over the moving parts from time to time.
The mg3 loves this, lack of oil kills this gat.
>>29568775
Such a complete disassembly is something only the armorer does during scheduled inspection and maintenance. No soldier in the field takes it apart like that, nor should he, nor is he being taught to. This is how it's done in the field (except that guy forgot removing the feed cover): https://www.youtube.com/watch?v=ON3Ui1Q6xl4
The bolt stays in one piece, just as it does during field disassembly of the FN MAG.
>>29568790
that's circular logic
>>29568812
Confirmed, exept that imho 150 is the usefullest barrel-circle-rate
>>29568791
Firing blanks causes more heat in the weapon than live rounds but, yeah, after that many rounds any MG requires a barrel change.
>>29562191
Gave me quite a chub. Not a full hard-on, but a nice chub.
Pros:
>High Rate of Fire
>Your receive Orgasm from shooting it
>looks hot
>absolutely based
Cons:
>heavy
>"where did I left the fucking barrel again?"
>putting the Fummelhülse back into its place is tricky with freezing hands
>cleaning it is annoying
And don't forget, Spannschieber comes first when putting everything together
I'll dump some MG3 pics I made
>>29567930
Roller delayed guns are very dirty. Talk to any G3/PTR owner.
>>29568863
It is in fact not, I gave you the reasons why I think it is what it is. If having arguments that back up my reasoning is too circular, what logic isn't?
>>29568930

>It is in fact not
Yes it is. It was the starting point of the reasoning here: >>29568192 and went full circle here: >>29568790
This means you tried to justify the claim with itself as reason. This is circular logic.
>>29568930

that cant be the official name for whatever part that is, oder?

No, the correct Term is rohrführungshülse.

I have plenty of experience with my beloved MG3. I User to be a gunner in kunduz back in 2009.
Im a german panzergrenadieroberfeldwebel, btw. If you are used to it, know to handle it, know its parts by the first Name, then it is the Best fucking thing you can have in real combat. I was the reargunner on our TPZ Fuchs, so it was mounted to a lafette. Next to no recoil, only the upward motion is to counter.
On foot, that thing gets heavy fast, but if you are in the Position to answer to the AKs tak tak taktaktaktak with the glorious RRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRET while your platoon advances towards the now freshly self-shat donkeyfuckers, this is just awesome.
Sure, it munches through its ammo like a tumblrina through cookiedough, but like murphy's warlaws sattes, it is physically impossible to carry too much ammo.
And no, you dont need tacticools like a scope, a frontgrip or crap like this on it. Well, not if you are a regular soldier anyways. I dont want to Talk in behalf of the ksk, These guys have the sickest shit... but I think for us normals, the standart Iron sight is just fine.
